GATA2 rs2335052 and also GATA2 rs78245253 single-nucleotide polymorphisms within Chinese patients together with intense myelocytic the leukemia disease.
TR severity was also significantly associated (hazard ratio = 1.33; p = 0.0002) with an increased risk of all-cause mortality. In conclusion, TR severity is significantly associated with an increased risk of all-cause mortality, independent of associated conditions including HF, OVD, or RSHD. In patients with severe TR, the mortality risk is most pronounced for patients who had RSHD without HF or OVD before their TR diagnosis.Right bundle branch block (RBBB) is one of the most frequent alterations of the electrocardiogram. Several studies have shown that RBBB is a risk factor of cardiovascular diseases. However, the clinical outcomes after pulmonary vein isolation (PVI) in patients with RBBB remain unclear. We enrolled consecutive atrial fibrillation (AF) patients who underwent PVI from the Osaka Rosai Atrial Fibrillation (ORAF) registry. We excluded patients with other wide QRS morphologies (left bundle branch block, ventricular pacing, and unclassified intraventricular conduction disturbances) and divided them into 2 groups RBBB (QRS duration ≥120msec) and No-RBBB (QRS duration less then 120) groups. We compared the incidence of late recurrence of AF and/or atrial tachycardia (AT) (LRAF) between the 2 groups using a propensity score-matched analysis and evaluated the risk of LRAF using Cox regression model. We finally analyzed 671 consecutive AF patients. The RBBB group consisted of 50 patients (7.5%) and the No-RBBB group of 621 patients. Median follow-up duration was 734 [496, 1,049] days. Hypertension and diabetes mellitus were significantly higher in RBBB group than No-RBBB group. Among the 46 matched patients pairs, Kaplan-Meier analysis demonstrated that RBBB group had a significantly greater risk of LRAF than the No-RBBB group (p = 0.046). The Cox regression model revealed significantly higher risks of LRAF (HR, 2.30; 95% CI, 1.00 to 5.33; p=0.044) in RBBB group compared with No-RBBB group. Non-PV AF triggers were significantly higher in RBBB group than No-RBBB group (p = 0.048). In conclusion, RBBB can be an important predictor of LRAF after PVI.Although higher body mass index (BMI) is associated with adverse left ventricular morphology and functional remodeling, its possible association with right ventricular (RV) dysfunction has not been extensively evaluated. RV free wall longitudinal strain (RVLS) is emerging as an important tool to detect early RV dysfunction. This study aimed to investigate the independent effect of increased BMI on RVLS in a large sample of the general population without overt cardiac disease. We examined 1,085 participants (603 men, mean age 62 years) who voluntarily underwent an extensive cardiovascular health check-up. This included laboratory tests and speckle-tracking echocardiography to assess RVLS. The association between BMI and RVLS was determined by logistic regression analyses. The prevalence of abnormal RVLS (>-19.2%) was greatest in obese individuals (29.7%), followed by overweight (16.3%), and normal weight (10.6%, p less then 0.001). In multivariable analyses, BMI was significantly associated with abnormal RVLS (adjusted odds ratio [OR] = 1.07 per 1 kg/m2, p = 0.033) independent of traditional cardiovascular risk factors, pertinent laboratory and echocardiographic parameters including RV size and pulmonary artery systolic pressure. In subgroup analyses, BMI was significantly associated with abnormal RVLS in men (adjusted OR 1.10 per 1 kg/m2, p = 0.032) and younger ( less then 65 years) participants (adjusted OR 1.13 per 1 kg/m2, p = 0.011), but not in women and the elderly. In a sample of the general population, higher BMI was independently associated with subclinical RV dysfunction. Furthermore, an increased BMI may carry different risk for impaired RVLS depending on the age and sex.Extracorporeal shockwave myocardial revascularization (ESMR) is a therapy for refractory angina pectoris. Our aim was to assess the efficacy and safety of ESMR in the management of patients with stable coronary artery disease (CAD) and heart failure as well as its effects on inflammation and angiogenesis. In this single-arm prospective trial, we included 48 patients with CAD, myocardial ischemia assessed by radionuclide imaging, echocardiographic evidence of left ventricular systolic dysfunction and without revascularization options. Changes in angina grading score, myocardial perfusion, left ventricular ejection fraction, and six-minute walk test after ESMR therapy were used for efficacy assessment. Changes of inflammation and angiogenesis biomarkers were also evaluated. ESMR therapy was performed using a commercially available cardiac shockwave generator system (Cardiospec; Medispec). https://www.selleckchem.com/products/mm3122.html After 9 weeks of ESMR therapy, a significant improvement was found regarding the initial angina class, severity of ischemia, left ventricular ejection fraction, and six-minute walk test in most patients. No deleterious side effects after treatment were detected. Regarding biomarkers, endothelial progenitor cells and angiopoietin-3 were significantly increased whereas IL-18 and TGF-β were significantly decreased after ESMR in the total group. Notably, VEGF, IL-1ß, and lipoxin A4 levels were significantly increased only in patients with myocardial ischemia improvement. In conclusion, ESMR therapy is safe and effective in most but not all patients with CAD and heart failure. ESMR is associated with increased markers of angiogenesis and decreased markers of inflammation. Myocardial ischemia improvement after ESMR is associated with increased markers of angiogenesis and pro-resolving mediators.Cyclophosphamide may cause hemorrhagic cystitis and eventually bladder urothelial cancer. Genetic determinants for poor outcomes are unknown. We assessed actions of fibroblast growth factor receptor (FGFR) 2 in urothelium after cyclophosphamide exposure. Conditional urothelial deletion of Fgfr2 (Fgfr2KO) did not affect injury severity or proliferation of keratin 14+ (KRT14+) basal progenitors or other urothelial cells 1 day after cyclophosphamide exposure. Three days after cyclophosphamide exposure, Fgfr2KO urothelium had defective regeneration, fewer cells, larger basal cell bodies and nuclei, paradoxical increases in proliferation markers, and excessive replication stress versus controls. Fgfr2KO mice had evidence of pathologic basal cell endoreplication associated with absent phosphorylated ERK staining and decreased p53 expression versus controls. Mice with conditional deletion of Fgfr2 in urothelium enriched for KRT14+ cells reproduced Fgfr2KO abnormalities after cyclophosphamide exposure. Fgfr2KO urothelium had defects up to 6 months after injury versus controls, including larger basal cells and nuclei, more persistent basal and ectopic lumenal KRT14+ cells, and signs of metaplasia (attenuated E-cadherin staining).
